We have a battery vacuum cleaner for cleaning up messes from small drillings and large vacuums that can even suck up fluids from bilges and areas inaccessible in other means to dispose of environmentally friendly rather than pumping overboard.

We have saws, pillar drill, and a lathe to enable us to carry out precision fabrications, tap and die sets metric, imperial, whit worth and bsp including some of the most unusual and rare threads used.
